Deaf child hears mother's voice, does "happy dance"

The sight of 3-year-old Kennedy Steele doing a happy dance is something her mother will never forget.

The little girl erupted in glee upon hearing the sound of her mother's voice for the first time. Kennedy, who was born deaf, is one of a small number of children in the U.S. testing a brain implant procedure that allows her to hear.

Kennedy was born without auditory nerves, so a cochlear implant, which helps some hearing-impaired people by stimulating the auditory nerve, was not an option for her. Instead she recently received an auditory brainstem implant, which bypasses what's missing in her inner ear.

This type of implant is already being used on older patients, and the FDA recently approved testing it in children at NYU Langone Medical Center in New York, where Kennedy had her surgery, and three other hospitals in Massachusetts, California and North Carolina.

"Early results are quite encouraging, " said Dr. J. Thomas Roland, Jr., chair of the department of otolaryngology at NYU Langone. "We think that these kids are getting auditory information and are on a trajectory to develop oral language acquisition and oral speech."
